MIAMI (AP) More than 1,000 people signed up to hunt Burmese pythons in the Florida Everglades, but just a fraction of them have been successful so far.

The Florida Fish and Wildlife Conservation Commission said Friday that 30 of the invasive snakes have been killed in the competition that began Jan. 12.

Wildlife officials say eradicating pythons from the Everglades was never the goal of the monthlong "Python Challenge." Instead, they hoped to raise awareness about the snake's threat to native wildlife and the fragile Everglades ecosystem. The snake faces both state and federal bans.

No one knows for sure how many pythons live in the Everglades. Researchers say the hunt is helping them collect more information about the pythons' habits.
